MD5, SHA-1, SHA-256 and SHA-512 of any text, computed live on your own device.

SHA-512
MD5 and SHA-1 are fine for checksums and cache keys but are not secure for passwords or signatures — use SHA-256 or SHA-512 there.
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the Hash Generator
Type or drop a text file.
MD5, SHA-1, SHA-256 and SHA-512 compute live.
Copy any hash with one click.
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Four fingerprints at once
A hash turns any input into a fixed-length fingerprint — handy for verifying that a download or a config has not
changed, for cache keys, and for deduplication. This tool computes MD5, SHA-1, SHA-256 and SHA-512 of your text at
the same time, updating as you type, using the browser's built-in crypto.
Reach for SHA-256 by default. MD5 and SHA-1 are fast and fine for checksums but are broken for security, so never use
them for passwords or signatures. To checksum whole binary files with drag-and-drop, use File
Hash.
Frequently asked questions
What are these hashes for?
Verifying a download hasn’t changed (checksums), cache keys, deduplication and building signatures. Each algorithm turns any input into a fixed-length fingerprint.
Which should I use?
SHA-256 is the sensible default. MD5 and SHA-1 are fast and fine for checksums but are broken for security — never use them for passwords or signatures; use SHA-256 or SHA-512 there.
To checksum a whole file?
This tool hashes text (and text files). For binary files and drag-and-drop batches with progress, use the File Hash tool.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
